You should at least try to understand how it goes wrong and make
sure that isn't true for the general case.

I have to disagree. Many machines here run through the same caching
proxy and the current system rarely has a cache hit, while the
earlier version almost always had hits after the first machine had
done an update. Or maybe I'm comparing the centos3 scheme to centos4.
I don't really know what has changed, but centos4 is as bad as fedora at
defeating what caching proxies are intended to do. Whatever you are
doing to choose an appropriate mirror is not at all consistent from a
given location so every subsequent request ends up pulling from a
different url. If what you are doing is correct, shouldn't it be
repeatable from the same location (i.e. through the same proxy)?

Maybe those claimed 1.5 million users are really a few users or
locations
with a lot of machines... Letting proxies work as designed would
make sense to me.

Users that are behind a common proxy generally know that, or the
proxy may intercept transparently. There's no particular reason to
think that this set of users know anything else about each other,
or what OS distribution the others might be using.
